so construct the door Be it known that T, VILLIAM' 0. Aurora,

in the county of Allegheny and State of Pennsylvania, a citizen ofthe'United States, have invented or discovered;-ccrtain new and usefulImprovements "in Doors for Coke-Ovens, &c.. of which inipro\-'ements thefollowing is a specification. 1 i

ll ieitivention described herein relates tocertain improvements in cokeoven doors, and hasjor its object a construction whereby the refractoryportion .of the door may be held securely in its supporting frame andthe latterprotected from the heat.

It is a further object of the invention to that ample draft 0 nmg may beprovided at the top of the ooi', such opening being formed by such anarrangement of parts, that it can be readily reduced orentirely closed.a

It is also an object of the invention to connct the door in sections sothat one part may be closedto'retain the coal in the oven while theother section is open to permit of the operation of the leveler.

The invention is hereinafter more fully described and claimed. 1 a

In the accompanying drawings forming a. part of this specificationFigure 1 is a front elevation of my improved door and its so portingframe detached oven Fig. 2 is an edge elevation of the shown the lines V5 isa detail v heart-h.

In the preferred construction the door is made in two sectionsindependently hinged to the-supporting post 1, which is firmly securedto the front of the oven by means of hooks 2 embedded in the masonry ofthe oven and having their ends secured to the post. The post has itslower end ste )ped in the sill or forehearth 3, as shown in i l and 2.The post is provided, where sectional doors are-employed, with a pair oflugs or cars 4 and 5 for each door section, and the frames 6 and f thedoor sections are provided with pairs of cars or lugs 8 and 9, so spacedwith reference to the ears on the post, that the pairs .of ears on thelatter will project bet-ween the members of the pairs on the doors orvice versa.

stability the front wall of the coke ovens is made quite thicket thebase and its front face give-n considerable batter. Hence in order thatthedoor sections may swingtogether and have a (good so bearing on theface of the wall aroun opening thereln, the lugs or ears on the post anddoor sections are so arranged that the the , pint-les 10 and 11 formingthe axes-of rota tion of the door sections will be in a. vertical 15plane at ri ht anglesto the fron't'wall but will be in iflerent verticalplanes at right angles to the first as clearl shown in Flg's. 1 and 2.The framesof t e lower Tsections are arched as shown in Fi being inwardand are provided with flan es or retaining walls Hand 15 along two si esand the bottom. The lining 16 is formed of bricks arranged in arch formon the inner surfaces of the frames and between the side flanges 14. Thebricks are supported vertically by the flanges 15 along-.the loweredgeof the frames. When the bricks exand under heat, they will becomemore tightly wedged in place,

keyed in place. When thus secured in lace arm jar or shock, especiallysuch incident to closing the door wi I not have anyloosening effect. Asshown in Fig. 4, theili'ning is extended above e .up frames, so as toprotect the latter from contj ct with the heat of the oven. The upperportion of the lining of the lower section \"iil protect not only the uper edge of the lower frame but also the i flange 15 of the upper sectionof the door. As shown in Figs. 3 and 4, the lining extends inward beyondthe side flanges 14 and the edges of such lining are designed to contactor nearly contact oven.

In order to revent injury to the lining when closing t e door sectionsthe latter are provided with'ibearing blocks or rojections 17, whichface of the oven. The blocks are desirably provided with holes 18 forthe insertionmf a hook for o ening the sections. The lower section can econveniently held closed by a bolt 19 placed in a hole in the sill and1057 the upper section can be lockedby a pin 20 inserted in a hole in aflange 21 on the lower section. In coking operations rovision must bemade for the a Patented Mar. 1.1910.

closing sii'ch opening.

In mg improved door this airinlet is formed y the arch shape of the dooritself. The forehearth or sill extends out under the lovveredge of thedoor, and the edges along the vertical sides of the door contact withthe front wall of the oven. These joints along the bottom '10?therewith, and by reason of the bowed ha anger the door a sector shapedopening is ormed atthe top of the door for the inflow of air.,This-opening may be partially or completelyclosed by placing brick on ofthe furnace.

In charging the furnace the lower section of the door is closed so as toprevent coal from dropping out. After (the coal is charged it can beleveled off, by a" suitable tool inserted throngh'the upper portion ofthe opening. I The upper section" 1s then closed and the joints h ted ifnecessary.

I claim herein as'my invention:

1. A door for coke ovens, etc having in I combination a snppoitidg.frame', and a lining,formed of agefractoryn aterial and l ',.;having anapproximately "uniform thick- 'ness hnd arched to withstand displacementby shocks or jars."

door for coke ovens, etc., having in combination a supporting frameprovided on opposite sides with retaining flanges and atlining ofrefractory material keyed between said flanges, the lining being concaveinwardly.

3. A door for coke ovens, etc, having in combination 'a supportingframe, and a limng secured thereto the inner face of the lining beingarched and a'pivotal connection "between" the oven and the doorsaidparts being'so arranged that the edgesat the ends of thea'rc'h will bearoil-opposite sides 'of the oven opening.

'A door for coke'ovens having in combination aframe and a plurality of doorasections adapted to be hinged to theframe, the axes of the door sections being indifferent verticalplanesand'at an angle to the plane of the door frame; In testimonywhereof, I have hereunto set my hand.
